Waiting for the BFP

So my husband and I have been ttc for 16 months now with no luck. In the meantime, I have been diagnosed with Hashimotos but was told that would not effect ttc. My TSH levels hang out around 2.3 so endo hasn't started me on meds.

My period is super regular and it's late! I've taken 2 pregnancy tests and nothing. I'm 1 day late and there is no sign of AF... Usually I start spotting right before. I'm seeing no 2nd line tho... So frustrating
